I live in Sandy Hill. It's not great variety wise when it comes to food. It's mostly pubs as you've discovered... Urban Well, Moon Dog, Friends and Sons, Drumlins, Royal Oak. There's a new shawarma place next to Friends and Sons if you're into that. Govinda's on Somerset offer a great vegan buffet for $8 ($5 for students) but I don't think they do lunch. Eclectic Noodle, a little further down will give you some pasta options but maybe a little pricey for lunch. I've never tried Acadie House, or Maison, or whatever it's called but it looks even worse than a pub. Same for University Tavern. Really, you'll have to venture to Rideau street to find anything out of the ordinary.
